1.动态问题的特点动态几何是研究几何图形在运动过程中,伴随出现的图形位置、形状、数量关系的“变”及“不变”性.动的对象常常包括点、线、面;动的形式常常包括平移、翻折、旋转、滚动等.从历年中考试题来看,动态几何问题一般作为中考压轴题目出现,一般得分率较低.动态几何问题往往集几何、代数知识于一体,综合性较强,题目灵活多变,动中有静,能够在运动变化的过程中发展及考查同学们的图形想 1. Characteristics of Dynamic Problems Dynamic geometry is to study the “” and “immutability ” of the relationship between the position, the shape and the number of the figure appearing in the course of the movement of the geometric figure. The moving object often includes points, lines , Dynamic surface forms often include translation, folding, rotation, rolling, etc. From the exam questions over the years, the dynamic geometry problems generally appear as the FFS axis title, the general score is low.Dynamic geometric problems tend to set the geometry, algebraic knowledge In one, more comprehensive, flexible subject, moving in a static, can change in the process of development and test students want to figure
